Enhanced Powerline Safety Settings

Enhanced Powerline Safety Settings (EPSS) allow your power to stay on during high-risk wildfire weather conditions by using settings that automatically shut off electricity the moment a problem is detected.

How EPSS works

To help protect our community during high-risk weather conditions, we are making our electric system smarter.

 

An infographic showing three levels of utility safety settings: Normal System Settings (multiple re-energize attempts during non-fire season), EPSS or Enhanced Powerline Safety Settings (no automatic re-energize attempts in non-reclose safety mode), and PSPS or Public Safety Power Shutoffs (proactive power shutoffs). The graphic notes that the utility does not implement PSPS. During extreme conditions, our main goal is to keep our community safe. We deploy EPSS to help prevent wildfires by keeping power lines de-energized—or turned off—if they’ve been damaged or come into contact with trees or wildlife.

Customers will only lose power if there is a direct safety issue, such as a downed line or equipment touching a tree branch. This prevents sparks that could start a fire. If this happens, we will inspect the line before restoring power. Depending on weather and terrain, this process can take four to eight hours. We move as quickly as safety allows.

What to expect

We continuously evaluate our safety protocols to ensure they align with current fire and weather conditions. We activate EPSS during high-risk conditions and deactivate EPSS whenever it is safe to do so to minimize service disruptions.

While the activation of EPSS can cause more frequent unplanned outages, it is a vital tool for preventing wildfires. These safety-driven interruptions will have no impact on your monthly charges. 

Questions and answers

 

Is EPSS always on?

EPSS is not always on. Each day, we check wildfire risk to decide whether to use them. Wildfires can happen any time of year, but are more likely from May through November.
